Virtual-reality-based interactions with virtual agents (VAs) are likely subject to similar influences as human-human interactions. In either real or virtual social interactions, interactants try to maintain their personal space (PS), an ubiquitous, situative, flexible safety zone. Building upon larger PS preferences to humans and VAs with angry facial expressions, we extend the investigations to whole-body emotional expressions. In two immersive settingsśHMD and CAVEś66 males were approached by an either happy, angry, or neutral male VA. Subjects preferred a larger PS to the angry VA when being able to stop him at their convenience (task), replicating previous findings, and when being able to actively avoid him (task). In the latter task, we also observed larger distances in the CAVE than in the HMD. CCS CONCEPTS • Human-centered computing → Virtual Reality; User studies.
